How to Convert Centimeters to Millimeters
Converting centimeters to millimeters is the smallest metric step: multiply by 10. Since 1 centimeter = 10 millimeters exactly, this conversion is used constantly in woodworking, medicine, and precision crafts where millimeter resolution matters.
1.00 Centimeters = 10.00 Millimeters
Multiply by 10 to get your result.
Step-by-Step
- Start with your value: 1.00 centimeters
- Multiply by 10
- Result: 10.00 millimeters
Formula: Millimeters = Centimeters × 10
💡 Memory Tip: 10 mm = 1 cm. Multiply centimeters by 10 — simply shift the decimal one place right.
